RCS2012F1911CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1911CS is a 1.91 kOhms ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is Active status and ROHS3 compliant. Substitute parts are identified when electrical specifications, mechanical dimensions, and environmental ratings align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F1911CS is valid when the following criteria are met:

Electrical Parameters (Critical):

• Resistance value: 1.91 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Variations in height (seated maximum) and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are functionally equivalent for direct substitution in applications requiring a 1.91 kOhms ±1% 0.125W 0805 chip resistor. Selection among these alternatives is based on availability, packaging preference, and specific application requirements:

CRCW08051K91FKEA (Vishay Dale): Carries AEC-Q200 automotive qualification. Suitable for automotive and high-reliability applications. Lowest seated height at 0.020" (0.50mm).

ERJ-6ENF1911V (Panasonic): Carries AEC-Q200 automotive qualification. Available in Cut Tape and Digi-Reel packaging formats. Highest seated height at 0.028" (0.70mm).

RC0805FR-071K91L (YAGEO): Standard industrial-grade thick film resistor. Moisture-resistant features. Mid-range seated height at 0.024" (0.60mm). Available in Tape & Reel packaging.

RCS2012F1911CS (Samsung Electro-Mechanics): Original part with anti-sulfur and moisture-resistant properties. Seated height 0.026" (0.66mm).

All parts maintain identical electrical performance across the specified operating temperature range and meet ROHS3 compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051K91FKEA replace RCS2012F1911CS in any application?

A: Yes. Both parts share identical electrical specifications (1.91 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package dimensions (0805), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). The CRCW part includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the packaging formats listed?

A: Tape & Reel (TR) and Cut Tape (CT) refer to supply formats. Tape & Reel is continuous reel packaging suitable for automated pick-and-place assembly. Cut Tape is individual tape segments. Digi-Reel is a proprietary reel format. These differences affect procurement and assembly processes but not component performance.

Q: Are the height variations significant?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm). These differences are within typical PCB assembly tolerances and do not affect electrical function. Selection based on height is relevant only for applications with strict clearance constraints.

Q: Do the anti-sulfur and moisture-resistant features of the RCS2012F1911CS require equivalent features in substitutes?

A: No. All listed substitutes, including YAGEO RC0805FR-071K91L (moisture resistant) and Vishay/Panasonic parts (AEC-Q200 qualified), meet or exceed environmental protection standards. MSL 1 (Unlimited) rating applies to all parts, indicating no moisture sensitivity concerns.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW08051K91FKEA and ERJ-6ENF1911V carry AEC-Q200 certification for automotive use. RCS2012F1911CS and RC0805FR-071K91L do not list automotive qualification but meet all electrical and environmental specifications. Application requirements determine whether AEC-Q200 certification is mandatory.
